The HI904 Karl Fischer Coulometric Titrator is an automatic titration system for the measurement of trace amounts of water in various samples. The Coulometric Titrator complements our wide range of titration products dedicated to efficient and accurate laboratory analysis. The HI904 analyzes for water content ranging from 1 ppm to 5%. This powerful titrator effectively monitors the Karl Fischer reaction, detects the endpoint, and performs all necessary calculations and graphing.

What is the principle of karl fischer titration

the actual principle is depend on mothod of detection

that is two type method 1,coulometary method 2,volumatry method both method are differ only in the delivery of iodine and,detection of water since we know one iodine molecules is consumed by one one molecule of water so if

we calculate how much iodine is reacted with water in sample then we can easily

calculate the amount of water(this…

Why only Water & Sodium Tatrate Is Use For THe Calibration Of Karl Fischer Titrator?

DST is primary standard and it is stable up to 150 degree Centigrade. It release free water molecules easily when reacts with KF reagent.DST is easily soluble in methanol. This DST has 15.66% water molecules so we can easily calculate and standardize the KF reagent. We use the factorof DST the compound which has less than 1% of moisture.

Water i.e 100% water molecules. But we must use 100%…
